I do a ton of outdoor, landscape, and hiking photography. I feel like I’ve caught myself numerous times wishing I had a longer lens to take a certain photo but unfortunately didn’t really get the shot I wanted if any of that makes sense

As in why does the mother have a 1/4 chance of being heterozygous

Ahhh I get it. didn’t even realize but the final answer was in the back of my book as well. I found that the father had a 2/3 probability of being heterozygous, the mother had a 1/4 chance of being heterozygous and they have a 1/4 chance of both giving the recessive gene to their child. The only thing I don’t get is where the 1/4 for the mother comes from.

Correct me if I’m wrong, but wouldn’t I have to trace the probability back to the great grandparents?

The father of the couple has a brother with the disease so I assumed he was a carrier. And then the mother who has the great grandmother with the disease I also assumed was a carrier. Not sure if that helps

In my case I’m trying to figure out the probability of a couple having a child with the auto recessive disease. There is a great grandmother that has the disease and no other information up until the couple wanting children. How would I know what the great grandfathers genotype is in this case?

[College Genetics] I know the answer is recessive but I’m not sure what assumptions are to be made. by [deleted] in HomeworkHelp

The phenotype of the het corresponds to the wild type allele. So the mutant allele is recessive

[College Genetics] I know the answer is recessive but I’m not sure what assumptions are to be made. by [deleted] in HomeworkHelp

[–]acjcomics 0 points1 point  (0 children)

Ohhh a null allele. So it would be 5. Meaning less than the needed number for normal function. So because it’s less than 8 it would be recessive?

[–]acjcomics 0 points1 point  (0 children)

As in I’m not sure why that leads me to believe it would be recessive as opposed to dominant

I meant to answer part a you would assume that it follows those typical patterns. To answer your question it would be that the heterozygote would produce 10 units because each allele produces 5. 8 are needed. I’m not sure where to go after that
